The Link Between Teeth Alignment and Migraines: Exploring the Benefits of Orthodontic Treatment


Thousands of people around the world suffer from migraine headaches, which can be debilitating. While the exact causes of migraines are still not fully understood, recent research has shed light on a surprising connection between teeth alignment and migraines. Orthodontic treatment, traditionally associated with straightening teeth and improving smiles, is now recognized for its potential to alleviate migraines. In this article, we will explore the link between teeth alignment and migraines, and explore the benefits of orthodontic treatment in managing this painful condition.

The Dental Occlusion-Migraine Connection

Dental occlusion refers to the way the upper and lower teeth come together when the mouth is closed. Any irregularities in dental occlusion can create a misalignment of the jaw, known as malocclusion. Malocclusion can lead to various dental problems, such as crooked teeth, crowded teeth, and an improper bite. However, recent studies have suggested that malocclusion can also contribute to migraines.

The temporomandibular joint (TMJ), which connects the lower jaw to the skull, plays a crucial role in dental occlusion. When the jaw is misaligned, it can put a strain on the TMJ, causing tension and discomfort. This strain can radiate to the surrounding muscles and nerves, triggering migraines in susceptible individuals. Additionally, malocclusion can lead to an imbalance in the bite force distribution, causing excessive pressure on specific teeth and leading to chronic headaches.

Orthodontic Treatment for Migraines

Orthodontic treatment, involving the use of braces, aligners, or other dental appliances, aims to correct dental misalignments and malocclusion. While orthodontic treatment such as clear aligners primarily focuses on improving dental aesthetics and functionality, it can also relieve migraines associated with malocclusion.

Let's explore how orthodontic treatment can benefit migraine sufferers:

Correcting Malocclusion

By addressing the underlying cause of malocclusion, teeth straightening treatment can realign the jaw and teeth, creating a more balanced dental occlusion. This can alleviate the strain on the TMJ and reduce the frequency and intensity of migraines.

Reducing Teeth Grinding

Many migraine sufferers also grind their teeth, a condition known as bruxism. Orthodontic treatment can help alleviate bruxism by improving the alignment of the teeth and reducing the chances of excessive grinding. This, in turn, can reduce the occurrence of migraines.

Improving Bite Alignment

Orthodontic treatment aims to achieve a harmonious bite, where the upper and lower teeth come together correctly. By improving the alignment of the bite, orthodontic treatment can minimize the uneven distribution of bite forces, which can contribute to migraines.

Muscle Relaxation

Misaligned teeth and jaws can strain the facial muscles, leading to tension and discomfort. Orthodontic treatment can help relax these muscles by realigning the teeth and jaws, providing relief from the muscular tension that often accompanies migraines.

Enhancing Overall Oral Health

Orthodontic treatment not only addresses dental misalignments but also improves overall oral health. Teeth that are straight are easier to clean, reducing the risk of gum disease and decay. Good oral health has been linked to a lower incidence of migraines, making orthodontic treatment a comprehensive approach to managing this condition.


In conclusion, the link between teeth alignment and migraines sheds light on the potential benefits of orthodontic treatment for individuals suffering from these debilitating headaches. Teeth straightening treatment, traditionally associated with enhancing smiles, can offer relief to migraine sufferers by addressing the underlying causes of malocclusion. However, it is important to note that it may not be a universal solution for all migraine sufferers.

Migraines have various triggers and causes, and orthodontic treatment may only be effective in cases where malocclusion is a contributing factor. Therefore, it is essential for individuals experiencing migraines to consult with both a qualified orthodontist and a healthcare professional specializing in migraines to determine the most appropriate course of action.


What is malocclusion?

Malocclusion refers to the misalignment of the upper and lower teeth when the jaw is closed. It can include issues such as overcrowding, overbite, underbite, crossbite, or open bite.

Is teeth straightening treatment suitable for everyone with migraines?

The treatment may be beneficial for individuals whose migraines are associated with malocclusion. However, it is essential to consult with an orthodontist and a healthcare professional specializing in migraines to determine the most appropriate course of action.
